Abstract

Systems, methods, and instrumentalities may be provided for an infrastructure node to transmit and a wireless transmit/receive unit (WTRU) or a group of WTRUs to receive a first downlink control information (DCI) a second DCI. The first DCI may carry time critical DCI, whereas the second DCI may carry non-time critical DCI. Each of the first DCI and the second DCI may be polar encoded. The second DCI may be polar encoded may be received with an embedded first DCI as part of frozen bits. The second DCI may be mapped to a plurality of bit channels having higher reliability than the plurality of bit channels to which the embedded first DCI is mapped. The WTRU may discard the decoded first DCI, if decoding of the DCI using the embedded first DCI is not successful.
